Title: Improvement in process of preparing alkylated phenols
IPC: C07C37/14
Filed: 1933-02-24
Abstract: Alkylated phenols and homologues and substitution products thereof, of the general formula R--R<1>--OH, where R<1> is a monocyclic or polycyclic aromatic or substituted aromatic nucleus and R is an alkyl group containing at least eight carbon atoms, are manufactured by treating a phenol or homolgue or substitution product thereof containing at least one free nuclear position with reacting proportions, preferably equimolecular amounts, of a compound of the group consisting of di-isobutylene, tri-isobutylene, di-isoamylene and higher homologues thereof in the presence of a strongly acidic material used as a catalyst in an amount substantially less than a molecular equivalent quantity, at a temperature which is unfavourable toward the permanent formation of the corresponding ethers, preferably below 70 DEG  C., e.g. at 0--25 DEG  C., in the presence or absence of an inert solvent, e.g. water, trichlorethylene, or carbon tetrachloride.  In examples: (1) phenol is reacted with di-isobutylene (obtained by treating tertiary butyl alcohol with sulphuric acid and probably consisting of a mixture of 2 : 4 : 4-trimethylpentene-1 and -2) in the presence of sulphuric acid to produce a -a -d -d -tetramethylbutylphenol (probably the o- or p-compound); the product yields phenates with caustic alkalies, e.g. sodium or potassium hydroxide, whilst with chloracetic acid in the presence of sodium hydroxide it yields a -a -d -d -tetramethylbutylphenoxyacetic acid; (2) o-cresol is similarly reacted with di-isobutylene to produce a -a -d -d -tetramethylbutyl-o-cresol; (3) the reaction of (1) is carried out using phosphorus oxychloride as catalyst; (4) b -naphthol and di-isobutylene are reacted by the method of (1) to produce a -a -d -d -tetramethylbutyl-2-naphthol; (5) p-cresol similarly yields a -a -d -d -tetramethylbutyl-p-cresol.  Other phenols and substitution products specified are: chlorphenols, cresols, chlorcresols, nitrophenols, phenylphenols, naphthols and phenolsulphonic acids. Other acidic condensing agents specified are: anhydrous zinc chloride, ferric chloride, aromatic or aliphatic sulphonic acids, phosphoric acid, phosphorus pentoxide and hydrogen halides.

Title: Improvements in or relating to methods of coating webs
IPC: B32B27/00
Filed: 1952-03-06
Abstract: 726,783. Coating webs; settable coatings on paper and films. KODAK, Ltd. March 6, 1952 [March 6, 1951], No. 5930/52. Class 140. In the manufacture of photographic sensitive materials, thin coatings of settable materials such as gelatine or polyvinyl alcohol are formed on flexible supports such as paper, by depositing on a rigid surface a thin, liquid coating comprising an aqueous solution of the settable material containing a spreading agent, causing the coating to set, pressing the support into contact with the set coating so that the support, which has a lower moisture content than the coating, absorbs some moisture to cause the layers to bond together, and stripping the bonded layers from the rigid surface. The setting may be effected by chilling or by chemical action. The spreading agent may be saponin, a non-ionic spreading agent such as polyethylene or polyglycol with an ester or ether grouping of a long-chain fatty acid. Certain anionic spreading agents such as an alkyl aryl sulphonate or a higher alcohol sulphate, prevent transfer of the composition from the rigid surface, but may be used if neutralized by a cationic spreading agent such as a quaternary ammonium salt, e.g., an alkyl pyridinium para-toluene sulphonate. Stripping may also be facilitated by treating the rigid surface, which may be that of a metal drum, with a fatty acid such as oleic or stearic acid, an alkali salt of one of these fatty acids, lauryl alcohol, dilauryl ether, or the traces of material left after buffing, or after cleaning with a household cleansing powder comprising a sodium aluminium silicate and a small amount of sodium palmitate oleate. As shown, a paper web 11 is unwound from a roll 15, led around guide rolls 16, 17 and pressed by a rubber roll 18 against a water-cooled, chromium-plated metal drum 13, on which a thin layer of an aqueous solution of gelatine and saponin has been deposited from a hopper 12 and set by cooling during rotation of the drum in the direction of the arrow. The combined layers pass as a unit over a short section of the drum, are stripped off at 22, and passed over rollers 23 to a drier. Instead of paper, the web may be a film or waterproof paper having an absorbent coating such as a layer of dry, unhardened gelatine. Instead of gelatine, the transferred coating may be an aqueous solution of polyvinyl alcohol containing resorcinol or α-naphthol. Examples of chemical setting are: (a) a solution of polyvinyl alcohol containing borax is set by fuming with ammonia gas ; (b) an emulsion containing gelatine may be set without chilling by adding formaldehyde before coating and fuming the applied coating with ammonia gas. The first easily-strippable layer applied to the drum may be covered with a further layer which would not strip if applied direct, and the two layers stripped together from the drum.

Abstract: 551,844. Converting STANDARD TELEPHONES & CABLES, Ltd. May 15, 1942, No. 6617. Convention date, Jan. 21, 1941. [Class 38 (ii)] [Also in Groups XXXVIII and XL] In an arrangement for producing impulses in a circuit 17 at the zero points of an A.C. supply 1, a battery 16, which produces the impulses, has its' voltage neutralized excepting near the zero points by the E.M.F. across a resistance 9 produced by the alternating E.M.F. The two, half waves of the A.C. respectively energize two circuits 5, 6. containing rectifiers 8, 12 and the common resistance 9 but the current through this and the voltage across it are prevented from, exceeding a certain amount by discharge tubes 18, 19. During most of the cycle therefore, the voltage across 9 due to the A.C. is kept at this amount, which is made equal to the 'battery voltage and there is thus no potential difference between the points 13, 15. At and around the zero point, the discharge tubes are non-conducting and the battery voltage overpowers the A.C. voltage across 9 and sends an impulse through the circuit 17.  In a development of the above arrangement, Fig. 3 (not shown), a particular phase of a multiphase supply may be selected and the im-. pulses are arranged to occur at the zero points of this particular phase.
